At Google and previously VMware/Nicira he has driven architecture and product security work at scale, now also serving on the Istio Steering Committee and leading its Product Security Working Group. His background spans research, patents, and production hardening of network stacks, and he blends deep protocol-level expertise with practical DevOps automation (notably contributions to both openvswitch and istio.io). Collected across academia (Stanford MS) and industry, his career shows a rare mix of founding-stage grit and long-term stewardship of critical open networking infrastructure.
